A growing wall of US corporate debt is set to mature from 2027, putting pressure on companies to refinance borrowings raised at ultra-low interest rates during the pandemic. About $4.3 trillion of non-financial corporate bonds issued in US markets will mature between 2027 and 2031, a Reuters analysis of LSEG data showed. Annual maturities rise from about $572 billion in 2027 to roughly $1.03 trillion in 2030, after many companies pushed debt into later years through refinancing.
